Season 1 Episode 2
America is a nation of vast distances and dense urban clusters, woven together by 200,000 miles of railroads, 5,000 airports, and four million miles of roads. These massive, complex transportation systems combine to make Americans the most mobile people on earth. Yul Kwon journeys across the continent by air, road and rail and ventures behind the scenes with the workers who get us where we need to go. At the Federal Aviation Administration command center, he listens in on a call with NASA, the secret service, the military and every major airline to learn how our national flight plan works today. He meets innovators who are creating ways to propel us farther and faster in years to come; in Las Vegas, he heads out into the wild night to see how transportation analysts are keeping traffic at bay by revolutionizing the use of one basic tool: the traffic light.
